A mono-energetic gamma-ray source based on laser Compton scattering is under development for non-destructive detection of nuclear material in cargo. In the detection system, we employ nuclear resonance fluorescence triggered by mono-energetic gamma-rays tuned at the resonance energy of nuclear material such as U-235. As a prototype, a 150-MeV microtron combined with a YAG laser to produce a 400-keV gamma ray is constructed at JAEA, where critical technologies are to be demonstrated for high-flux gamma-ray generation, 3x10⁵ ph/s. We also start to design a microtron at higher energy, 250 MeV, to produce a 2-MeV gamma-ray, which is required for the detection of U-235.
